Specification of Letters Patent.

Patented. Feb. 27, 1917.

Application filed September 28, 1916. Serial No.-122,584.

' the following is a specification.

This invention relates to an improved form of umbrella, the object of the invention being to provide an umbrella which is very strong and which can be collapsed into small space.

The invention consists, primarily, in providing ribs, each of which constitutes a lazytongs.

Furthermore, the invention consists in an improved collapsible handle.

Finally the invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof. Referring to the drawings: Figure 1 is a sectional elevation illustratingthe handle and standard of the invention with one of the lazy-tong ribs extended. Fig. 2 is a plan view broken away to save space.

Fig. 3 is a sectional elevation showing the umbrella closed and the handle collapsed.-

Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 3.

Fig. 5 is a sectional detail illustrating the manner of locking the umbrella in its open" position.

Fig. 6 is a sectional elevation illustrating the means for locking the tubes of which the handle is formed together.

Fig. 7 is a detail section taken on line 77, Fig. 1.

Like numerals refer to like-parts throughout the several views ofthe drawings.

In the drawings, 10 is the standard within which is inclosed a handle 11 when said handle is in collapsed position. The handle 11 consists of three tubes 12, 13 and 14 arranged to slide telescopically one upon the other.

When the handle is in extended position as in Fig. 1, the tube 14 is locked to the tube 13 by a pin 15 (see Fig. 6) and the tube 13 is locked to the tube 12 by a pin 16. The tube 12 slides telescopically upon a stationary inner tube 17 which is fastened to the standard 10 and a plug 18 in the upper end of said standard by a cross-pin 19 (Fig. 3). The tube 12 is fastened to the stationary tube 17 when the parts of the handle are in extended position by a spring-actuated pin 20.

The upper ends of the tubes 12, 13 and 14 are provided with holes 21, 22 and 23, 1

respectively, (Fig. 3). The locking pin 20 is supported upon a spring 24 fast to the inside of the stationary tube 17. The looking pin 16 is supported upon a-spring 25 fast to the interior of the tube 12.- The locking pin 15 is supported upon a' spring 26.

fast to the interior of the tube 13.

The tubes 12, '13 and 14 are kept incorrect alin ement so that the pins 15, 16 and 20 enter the proper holes in the tubes 12, 13 and 14 by pins 27, 28 and 28 on the tubes 12, 1-3 and 17 which project into slots 29, 30

and 30, respectively, in the tubes 13, 1'4 and 12. The pins 15, 16 and 20 are beveled off on their outer ends for a purpose hereinafter described.

A series of lazy-tongs 31, each of said lazy-tongs constituting a rib for the umbrella, are pivotally mounted upon the standard 10. The inner end of the link 32 of the innermost pair of links forming the lazy-tongs is pivoted at its inner end at 33 to asleeve 34 which is fastened by the pin 19 to the standard 10, whereby the lazytongs are pivotally mounted on said standard 10, while the other link 35 of said pair ispivoted at 36 to a sleeve 37 which is slidable on the standard 10 and is locked in position when the umbrella is open by a spring-actuated lever 38 pivoted at 39 to said sleeve 37, the lower end of said lever.

lazy-tongs are pivoted together in the usual manner, as shown. It will be noted, however, that the distance from the pivot 41 to the pivot 43 is greater than the distance from the pivot 41 to the pivot 42 and that the distance from the pivot 46 to the pivot 47 is greater than the distance from the pivot 46 to the pivot 48, the object of this construction being to cause the lazy-tongs to assume a downwardly inclined position when they are extended as shown in Fig. 1. The covering 49 of the umbrella is fastened to the outer ends of the lazy-tongs as at 50 and 51 and the central portion of said cover is clamped between the collar 52 and a rotary spring-inclosing member 53, said member 53 being rotatably supported upon the stationary inner tube 17 and extended upwardly to form the usual top spindle 54 of the umbrella. \Vithin the rotary member 53 there is located a spiral spring 55 the inner end of which is fastened to the stationary tube 17 and the outer end of which is fastened to the inside of the rotary member 53.

The general operation of the device hereinbefore specifically described is as follows: Assuming the parts to be in the relative positions illustrated in Fig. 3, that is, with the umbrella closed, the umbrella is opened by pulling the tube 14 downwardly by means of a knob 56 which is attached thereto. Vhen the tube 14 has been pulled out far enough to bring the hole 23 in alinement with the pin 15 the spring 26 will cause said pin to enter said hole and the part 13, to which the spring 26 is fastened, will then move with the tube 14 downwardly until the hole 22 in said tube 13 alines with the pin 16, whereupon said pin 16 will be moved into said hole by the spring 25 and the tube 12 will then be drawn downwardly along with the tubes 13 and 14 until the hole 21 in the tube 12 alines with the pin 20 which is connected by the spring 24 to the staionary tube 17. The handle is then extended as shown in Fig. 1.

The sleeve 37 is then pushed upwardly expanding the different lazy-tongs which carry with them the covering 49 until the parts assume the position illustrated in Fig. 1. During the expansion of the lazy-tongs and of the cover 49, the member 53 will be rotated by the covering 49 which is coiled around it, thus winding up the spring 55 and the umbrella will be locked open by the lever 38, the lower end of which enters the hole 40, in the standard 10, as illustrated in Fig. 5.

To close the umbrella, the lever 38 is disengaged from the hole 40 in the standard 10 by pressing against the upper end of said lever; the sleeve 37 is then pulled downwardly on the standard 10 until the different lazy-tongs constituting the ribs of the umbrella have been collapsed, as illustrated in Fig. 3. During this collapsing of the umbrella a portion of the covering will assume a position between the lazy-tong ribs and the slack of said covering will be taken up and woundaround the rotary member 53 which is rotated by the spring 55, said spring having previously been wound up, as stated, by the opening of the umbrella.

The handle is shortened from the position illustrated in Fig. 1 to that illustrated in Fig. 3 by pressing inwardly on the pin 15 and pushing upwardly on the tube 14.

The pin 15 is pressed inwardly to a suficient extent so that when the tube 14 is moved upwardly the lower edge of the hole 23 in said tube 14 (see Fig. 6) will engage the beveled outer end of the pin 15 and ,force it inwardly to the position illustrated in Fig. 3 and the tube 14 will then slide up on the tube 13 until the upper edge of said tube 14 encounters the beveled outer end of the pin 16 which will then be forced inwardly and the tube 13 can then be pushed up, along with the tube 14, and'the lower edge of the hole 22 in the tube 13 will engage the beveled outer end of the pin 16 and force that inwardly until said tube 13 is released so that it can slide upwardly on the tube 12. The upper edge of the tube 13 will then engage the pin 20 and cause it to be retracted so that the tube 12 can slide on the tube 17 ,and thus all of the tubes will be pushed upwardly Within the standard 10 until they assume the relative positions illustrated in Fig. 3.

It will be noted that the pins 15, 16 and 20 are beveled on the under sides of the outer ends thereof, so that while they can be retracted by pushing upwardly on the tubes they will form a lock to prevent the downward movement of said tubes relatively to each other after said pins have been sprung into the holes therein.
